Originally posted by jankok I've noticed in your profile that you have the Voigtländer 125 and the Pentax FA 100 macro. What are the differences (besides the obvious ones, i.e. autofocus, ...). I would also value your subjective opinion about the images produced by both lenses (resolution, CA, bokeh, ...). Maybe you can post a sample fom both?
Is it true (as can be concluded from photozone.de reviews) that the Pentax upholds the resolving power better at smaller apertures (i.e. f/16 and f/22)?

sorry I have only owned the Voigtlander for about 1 week now and I have been too busy to do anything besides mess around indoors with it so far.
but I do plan to compare these two, I will have to consider if I should keep them both or sell one of them. Then again the FA has autofocus which can be usefull but I rarely use AF, I use MF with a split prism focusing screen. But if I am shooting something moving or its too dark to use the prism then I turn to AF, so I still apreciate having the option.
when I get time I will try to compare these and post. I can tell you I think the FA 100 is a very nice lens, both as a macro and as a Tele, I have actually used it more as a Tele, since I didnt have a tripod when I got it.
for now I can say something about how it is to use:
- the VL handles nicer and feels lighter, I think in part because it is shorter so the weight is close to the camea
-the MF feel of the VL is a lot better, I love the feel of the VL ring, its not too stiff not too loose, the FA is known for having a bit slarky MF ring, it has a focus clamp that you can turn to increase resistance on the MF ring to make it stiffer, I always keep it at max stiffness when i MF, and then its OK. Also on the VL the whole barrel is the MF ring so its nice to use, the FA has the MF ring at the tip so you have to extend your arm a bit to grab it, with the VL I can hold my focusing hand closer to the camera body, making it feel more stable.
now obviosuly I had the FA and bought the VL so I must think the VL is better, at least from other peoples pictures right? To me the VL has something special, a unique look, a combination I think, of lack of CA and other defects combined with extreme sharpness, making the images very clean and crisp. also i think there is something with the colors. hard to describe, thats one reason why Id like to do a comparison later on.
